Giovanni di Balduccio
Giovanni di Balduccio (c. 1300 – c. 1365) was a Pisan sculptor. Trained in Pisa's cathedral workshop, he signed work at Sarzana in 1327 and at San Casciano in 1330–1331 before Azzone Visconti called him to Milan around 1334.
There his signed marble shrine of Saint Peter Martyr in Sant'Eustorgio, dated 1339, is his masterpiece. He declined the mastership of Pisa Cathedral in 1349, and some scholars also credit him with the Arca di Sant'Agostino at Pavia, built 1362–1365.
